littu lmown thatv l, VLoris RENAULT, engi- -ttvzen ot the French lepuhlie, resid neer, :it git!- at lillaneourt, De )artment ol the Seine,

antw. have invente( eertaui new and usel'ul imprmeiuents in tarburtters. ol" which the loll \'.i.'n is a spet'ilit-ation.

'l lus invention has lor its object to provide a rarluueter havingr a variable suppl): and in luth the passages tor the air and liquid hytrovai-hou eau he sunultaneously and protort ionatelj.' inereased or decreased either by merlmnieol means operated bv hand or automatit'allj,Y in proptution tothe degree ol vat-uum treated iu the sortiert-pipe ot` the earburoei:

The earbureter, Fig. l, comprises a eliamher t. eontaining liquid hydroearlion at a eonstant level, and an air-Chamber 2, closed at its upper part hv a cover f3. provided with an opening it, through whit-h air enters the eltamber. i\.= the uiier wart of the rhamber '2 is .wronged a roniral trlunnel-shaped mem- "r :'i. inside o'hith a dislt` t) ran be moved )t up and down lo means ol the bell-erarflt T. 'Th' under stdlol the dislt t3 is provided with a li .llon o vltndt'r N, slidingr smotrthlvr in t i ai! rounding :t mojertion inward from the ol' the ehamher i?. (lu the top of the projection rests a sprriving-nozzle ll, vided Willi s'eitt'nl :igt-s il? lli ll. al'- rane'ed at ditlerent heights and lorniingeommunieatlou lrv rl1amb-1-rsl and 'lhe upper part ol the ovlinder b is provided vvit li openings l lor permitting thtl ail entering' by the openingr l passing into the Mlioder A. lirom ,vheure it passes into tht` .starre lT nl' the ehamber 2, from Whenee. it passes into the suction-pipe oll thtmotor.

l 'The eonoidal part, it) enables the passage from the rvvlinder Y to the spatie t7 to be rompletely closed; but ill the (f vlinder and disk tl 1be raised by means ot' the bell-(frank T an air- ;.tassa-e is obtained the tfrosssseetional area.

side of the cylinder S also increases.

eration of the Cylinder S permits of inereasof whit'lh is pro ortional to the lift of the said rvlinder and diisk. 'heu the @oss-section of the passage for air from the cylinder S to the spare 1T inereases, the erossssertion of the air-passage from the chamber 2 to the in- 'lhe oping prt)portionatelv the cross-seetimi of the passage eomprised between the Funnel-shaped member 5 and the eonoidal part lO,

The disk (j Carries at its center a second oylinder IS, the upper )art ot which passes through the cover 3 and is in communication with the atmosphere through the opening 19.

i The lower part of the Cylinderl isof reduced internal diameter am can slide smoothly over the sprayinhf-nozzle. According as the disk t3 is more or less raised, a greater or lesser number of outlets for the liquid hydrocarbon is uncovered aud subjected to the suction produced in the Cylinder 8. When the disk 6 at tht` lower end ofitsstrolte-that is, when the cylinder 8 intercepts the passage between the inside of this cylinder and the space 171- the liquidhydroearhou outlet 12 is in communication with the inside of the cylinder S, vrhle the other two passages 13 and M for the liquid hydrocarbon are covered by the tube IS, and therebj,r put. in eonunuuieation with the atmosphere through the opeuner 19 and are eonsequentlv entirelyY unalleetedJ by the suction-stroke of t he motor-pistom ll the disk 6 be raised hv means of the bell emnlt T, the ainpas age around the spraying-- iozxle li increases as the disl; rises` while at the same time the suppl)F of liquid hydrocarbon increases proportionately. because the lower part. ol the tube lla' uncovers sut-cessubjeeted to the suetion ereated in the cham- V1n order to render the Carbureter automatie in notion, itis. necessary to substitute for the operating-lever 7 means whereby the eylinder and disk t, Fig. 2, are raised by suc tion in the earbureter. For this purp'ose the disk tj, movinzgY in the conical part 5" olthe earhureter, is made very large` so as to present a largo area to and be more efficiently rlhe movement ol the dislt is regulated by means of a screwbralie itl to prevent the disk movingr too suddenlv.

Having now pitrtieularlv desrribed and ascertained the nature ol my invention and in IOO qui

what manner the same may be performed, l declare that what I claim is l. Aearburetei comprising a mixing-chamber, a s raying-nozzle provided with a plurality o' outlet-passages of di'fl'erent lengths, said passages communicating with the mixing-eliamber anda hydrocarbon -supply, a funnel-shaped-i-nember arranged Within the mixing-chamber, a Vertieally-movable disk arranged Within the mixing-chamber, a eylindrieal member carried by said. disk, positioned within said funnel-shaped member and having openings in the side thereof, and means carried by said disk for elosing certain of the outlet-passages of the nozzle and for establishing communication between the passages and the atmosphere.

2. A earbureter comprising a mixing-oliember, an air-inlet therefor, a chamber surroundingr said mixing-chamber and adapted to ei'nnmnieate therewith, an outlet for said last-mentioned chamber, a vertically-nievi able cylindrical member adapted to open and elose communication between the'tWo chambers7 a nozzle efstending within said mixing- :.5 Chamber and provided with a plurality of outlet-passages of different lengths opening into the mixing-chamber and eommunieatinw with a hydroearbon-supply, a verticallymoyable disk attached to said cylindrical 3o member, means carried by the disk and surrounding the nozzle and adapted to elose oertain 'of said passages to said mixing-chamber and to establish communication between said passages and the atmosphere., and means 3 5 for vertically moving said closure. means, thereby imparting a like movement to the disk and cylindrical member.

In testimonyY whereof I have hereunto set my baud in presence of two subscribing wit- 4.o nesses.
